Lay the pricing pages of eight companion apps next to each other and you will see the same dozen bullets repeated. The products behind them could hardly be more different. Each claim below is technically accurate for every app, and each conceals a spread wide enough to decide whether you will enjoy using it.
"Memory" or "remembers you"
The spread: from a short list of facts resent with every message, right up to stored facts plus running summaries plus a retrieval system that copes with months of history.
Both get called memory, quite fairly. The distance between them is the distance between an app that is fun for a week and one that is still fun in month four. The mechanics are covered in how AI companion memory works.
The question that settles it: can I view and edit what it has saved? A memory screen tells you the storage is real and organised. Kupid AI lists memory across sessions, and Nomi is built around it, which is how it earns its conversation score in our ranking.
"Unlimited messages"
The spread: truly uncapped text, or uncapped text under a rate limit, or uncapped text on one plan with media metered on every plan.
The promise is usually honest and usually misread, because text is not what costs the operator money. Pictures and voice carry a real cost each time they are used, so that is where the meter goes.
The question: unlimited what, precisely, and what still uses credits?
"Voice"
The spread: from the character reading its replies out as audio clips, to a live back-and-forth conversation where you can interrupt.
Two different products share one word. Clips are cheap and everywhere. Live calls cost more, generally sit on a higher plan, and rise or fall on delay: a three-second gap before every answer kills the effect.
The question: is this a call or a clip, and how long is the lag?
"Uncensored" or "no filters"
The spread: from looser than the mainstream to a good deal looser than the mainstream. Never actually unfiltered, since every operator blocks the same illegal core and card processors insist on it.
The question: where does the limit fall, and has it shifted lately? More in content filters.
"Custom characters"
The spread: a choice of four hair colours and three personalities, up to a multi-step builder that covers looks, voice, backstory, manner of speaking and off-limits topics.
Depth here tends to track how long the app stays interesting, because a character you built yourself is one you can rebuild when it goes flat. Camsoda AI is built around a six-step builder, which is a real product difference and not just a bullet.
The question: can I change the character after making it, or only during setup?
"AI image generation"
The spread: a new face on every request, up to a character who stays recognisable over dozens of pictures.
Consistency is what matters most, and a pricing page cannot show it.
The question: if I ask for four pictures of one character in four situations, is it the same person?
"Builds a relationship" or "grows with you"
The spread: a relationship meter that ticks up with use, versus a character whose stored history truly changes how it answers.
Progress bars are cheap to build and easy to confuse with depth.
The question: what actually changes at level five, described in words?
"Free plan"
Every app we follow has one. What varies is whether it is something you could live with for months or a three-day teaser, and what free tiers really include sorts the two.
The question: what does the wall say when I reach it: a daily allowance, or a nudge to upgrade?
What sits under all of it
Each claim above names a category and says nothing about the build, and the build is where the product lives. That is why comparison tables in this market are close to useless, and why we test the way we do: a fortnight on a paid account shows which end of each spread an app is actually on.
If you only have ten minutes, two shortcuts. Favour the app with fewer, deeper bullets, because wide tends to mean thin. And favour the one that lets you look inside: a memory screen, an editable character, a visible credit balance. Apps that show you the workings nearly always have workings worth seeing.
